Bastustenar Round Olivine 20 Kg

For SPIRIT Series heaters only.

The heater’s design highlights the round stones, creating a modern but elegant atmosphere with gentle steam. Equipped with WiFi, the heater is easy to use. Harvia Spirit is the spirit of your sauna that guarantees a soft and enjoyable experience. 

The use of round Olivine Diabase stones introduces a soft steam method; water runs easily down to the lower stone layers reaching more surface area, generating more steam with a softer touch. 

The use of larger stones in the bottom layers is recommended as they give more heating surface area. This provides the best result for effective heat generation.

If larger 10-15 cm diameter rounded stones are used, finish the top layer of the heater with smaller 5-10 cm diameter stones to guarantee the softest steam.
